Funny you should ask...
I happen to spend a great deal of my writing time in a post-apocalyptic world so I think about this stuff a lot. I hope we never get to this point, but it's fair to say that in our history we've never NOT used a weapon we've invented. Think about it.
Accurate estimates are hard to come by, but there are perhaps 10,000 - 20,000-ish nuclear weapons in the world. Each capable of killing hundreds of thousands of people.
When I think about the "end of the world," I envision alien forensic scientists from two galaxies away one day finding our fingerprints all over the trigger. Whether it's nuclear war, bio-weapons resulting in world-wide plague, and/or global warming that leads to an uninhabitable environment, our actions have the potential to make life on this planet...well, the sort of thing only storytellers can imagine.
Every year they warned about the flu and more often than not, it amounted to nothing. Sidney Knight, a young freelance reporter had certainly never written on it. But a trip to Lincoln City, Oregon cut short by a beach full of dead seagulls and a panicked warning from her brother the scientist catch her attention. This batch is different. Deadlier. And the vaccine doesn't seem to be helping. It almost looks like it's making it worse...
A Flock of Ill Omens: Part I is the first episode of A Shot in the Light, an Apocalypse Conspiracy Tale about what happens when people play God for fun and profit. There will be approximately ten episodes, each the equivalent of about 100 pages.
Find A Flock of Ill Omens at Good Reads and Amazon.
Hart Johnson writes books from her bathtub and can be found at Confessions of a Watery Tart, though be warned. She is likely to lead you into shenanigans.
And with that...Have a great weekend! :)
